CAN-FILLING MACHINE.

Application filed March 24, 1927. Serial No. 177,871.

My invention relates to can filling ma chines and more'particularly to amachine, such as that covered by Patent No. 1,533,536, issued to me on-April 1 31925, which is adapted-to simultaneously deliver measuredquantities of vegetables and brine or liquor into cans. I

This machine is adapted to run at a high rate of speed, and deliver theliquor into the cans withoutsplashing so that it is unnecessary to sealthe can whileit isreceiving its charge of brine. However, the brine cupsenter the liquor in the tank at such'speed that the air contained inthem does not have sufficient opportunity to, escape, and thus causessplashing of the liquor in the tank itself. 8 r

The object of my invention'is to provide simple means whereby the brinecups may be filled gradually from the bottom, without interfering withthe speed of'the machine,

' and the air may escape freely from the top of the cups.

This object, and other advantageous ends which will be describedhereinafter, I attain in the following manner, reference being had tothe accompanying drawings in which Figure 1 is a central verticalsectional view of a canning machine, similar to that shown in Patent No.1,533,536, on which my inven-,

tion has been installed; the lower part of the machine having beenomitted.

Figure 2 is a view takenisubstantially on line 22 on Figure 1 but withthe displacement member omitted, and

' Figure 3 a view similar to Figure 2 but with the brine measuring unitomitted.

Referring now more in detail to the drawings, the machine is providedwith a hopper 5 into which the material to be canned is placed and whichis supported on a hopper plate 6 resting on the topsection 7 of themeasuring wheel. A bed plate 8, which is suitably secured to the frame9, supports the lower section 10'of the measuring wheel while topsection 7 is supported on a shaft 11 and adapted to be raised andlowered, relatively to lower section 10, by means ofa screw 12 threadedthrough an extension 13, formed on upper section 7, and abutting the topof shaft 11. Lower section 10 is keyed to shaft 11 and adapted to makecontact with the top of bed plate 8 as it rotates while the top ofsecformed in, hopper plate 6 and are adapted to discharge their contentsthrough an opening 16 formed in bed plate 8 and communicating with thefunnel 17 which directs the materialinto cans 18 fed thereunder in thewell known manner. It is evident that raising and lowering top section 7by means of screw 12 will change the cubical contents of measuring cups14 and consequently regulate the measured quantities delivered to cans18. In orderto avoid crushing the material on the tops of measuring cups14 and to provide for inequalities in sizes of the material beingcanned, I provide a relief channel 19 which extends from hopper 5 to apoint above-disliquor are directed into cans -18, simultaneously withthecharge of granular material,

through a chute 20 communicatingwith a brine measuring device by meansofa pipe 21.

The brine feeding mechanismincludes a brine tank 25, a bed plate 23,mountedat'an incline to the horizontal and having its lower endextending into the tank and substantially to the bottom thereof. A disk29, keyed to aninclined shaft 28 is rotatable upon bed plate 23 andcarries a series of openended brine'measuring cylinders 30. The disk,like the bed plate, extends substantially to the bottom of the brinetank so that rota-- tion of the disk carries each cylinder downwardlyinto the brine tank, then upwardly out of the brine to a dischargeopening 36 inthe bed plate through which the measured quantity of brineis discharged. The inner [ill may be regulated by raising and loweringdisplacement member 32 by means of screw '34.

Brine cups 30 are filled by rotating disk 29 and plunging the cupssuccessively into the liquor in tank and the liquor is retained in thecup by reason of the fact that the bottom of disk 29 and the top ofplate 23 are ground or otherwise suit-ably finished so as to preventleakage of liquor from the bottoms of the cups.

7 As disk 29 is adapted to rotateat a hi h speed, cups 30 are violentlyplunged into tie liquor in tank 25, so that but little opportunity isgiven for the air contained in them to escape, with the result that theliquor is splashed and churnedand, when the level of the liquor iscomparatively low, the cups are not evenly filled. To overcome thisobjection, I form a recess 37 in the'upper face of the low part of thebed plate. Therecess is in that side of the bed plate over which thebrine disks travel in their downward movement and preferably extendsrearward about one half the length of the plate and inward toapproximately the same distance. The recess communicates with the brinetank andwith the brine cup as the brine measuring disk travels over it,and serves as a feedchannel. The result is that the brine cup isgradually submerged and gradually filled from the bottom as it passesinto the brine. There is therefore no splashing and the air, instead ofbeing trapped within the cup, passes out freely at the top. As thecups'leave channel 3?, the liquor is effectively held against leak agetherefrom by the bottom of disk29 sliding on the upper surface of plate23 until the bottoms of the cups come into registry with opening 36 whenit is discharged through this opening and directed into cans 18 by wayof pipe 21 and chute 20; it being led into the can at an angle so thatthe can is evenly filled with granular material and brine with out anysplashing of its contents.

While I have described my invention as takingla particular form, it willbe understood that modifications may be made without departing from thespirit thereof, and hence I do not limit myself to the.rec-ise-eonstruction set forth,- but considert at I am at tendingupwardly from itslower ledge under the downward path of travel of the brne .cyl-

inder. I
